Failed Delivery Cost Calculator — True Cost of Missed Deliveries

Calculate the true cost of every failed delivery attempt. Redelivery trips, driver time, customer service contacts, and potential lost customers — the numbers add up fast.

Quick answer: Failed delivery costs: $6–$15 in direct costs per missed attempt (driver time + fuel). Add customer service contacts ($5–$12 each) and customer churn risk and total impact reaches $30–$100 per failed delivery.

How to Use This Calculator

Enter monthly delivery volume — total first-attempt delivery attempts.
Enter failure rate — percentage of first attempts where delivery is not completed.
Enter direct costs — redelivery trip cost and customer service contact cost.
Set CS contact rate — what percentage of failed deliveries result in a customer service contact.

Worked Example

2,000 deliveries/month, 8% failure rate, $9.50 redelivery, $8 CS contact, 60% CS rate.

Failed deliveries: 2,000 × 8% = 160/month
Redelivery cost: 160 × $9.50 = $1,520
CS contacts: 160 × 60% × $8 = $768
Total monthly: $2,288
Annual: $27,456

Reducing the failure rate from 8% to 4% through SMS notifications and delivery windows would save $13,728/year. The technology to enable this (SMS APIs, delivery notification systems) typically costs under $3,000/year for this volume.

Frequently Asked Questions

Common causes: recipient not home (residential), address errors, gate/access codes missing, business closed, delivery window not communicated, and package size too large for letterbox. Pre-delivery SMS/email with ETA and one-click reschedule reduces residential failure rates by 40–60%.

Safe harbour (or safe place delivery) allows drivers to leave packages in a designated secure location without a signature. This eliminates failed deliveries for absent recipients at the cost of some liability. Most carriers require customer opt-in. Effective for reducing failure rates in suburban/residential areas.
